Research in the area of critical thinking ability many times involves the use of the Watson and Glaser Critical Thinking Appraisal (WGCTA). These abilities involve inference or drawing conclusions from facts or premises, recognition of assumptions or hypotheses, deduction or working from basic premises to conclusions, interpretation of data to derive or explain its meaning, and the evaluation of arguments or evidence. The items on this instrument are not specifically limited to science. As a result, when researching the effect of an instructional procedure in science, the teachers and all other subjects the students are exposed to need to be controlled.
